Simultaneous redundancy is achieved by operating 750-882 over two networks, which are accessible via two different IP addresses and MAC IDs. The independent ETHERNET ports permit redundant connection of two transmission paths. If Port 1’s path fails (e.g., broken cable), Port 2 serves as an alternate. If redundancy is not required, networks are addressed separately for intra-network data exchange, e.g., from shop floor machinery to a top floor Manufacturing Enterprise System.
